Video Settings
This lets you set the performance characteristics of your cameras
and streams.
When finished, be sure to click Save .
On the Luma DVR, you can also use Copy to... to duplicate that
stream’s settings (only) from the selected camera to other cameras.
Camera and Stream Selection
Channel No. lets you choose which camera (channel) you want to
adjust.
Video Format shows the camera’s best resolution capability (this
does not appear on NVR models).
Stream Type identifies whether you are editing the settings for the
main stream for that camera (used when observing that camera’s
view by itself) or the sub stream for that camera (used when
observing several cameras in grid mode).
You can also select whether the main stream is being used for
normal surveillance or for recording during an event. The Main
Stream (Event) setting is derived from the normal setting, except you
can adjust the frame rate and maximum bitrate.
Settings
Below the divider, you adjust the settings for the selected camera
and stream. With the NVR, note that many settings for sub stream
cannot be edited if the camera is not capable of accepting those
edits.
Video Type: Determines whether you want audio (if the selected
camera is audio-capable).
Resolution: Determines the quality of video delivered. The data in
these fields are automatically detected from the individual camera
features, although you can adjust the resolution you want. You can
set the camera’s resolution down from its rated resolution if you
need reduced bandwidth.
Bitrate Type: Lets you choose whether you want the system to adjust
how much data it sends based on bandwidth (variable) or whether
it should always send a fixed amount of data (constant). The
